METAL WINDOW-SASH.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed October 20, 1906. Serial No. 339,783.

To all whom it may concern:

Be it known that I, ERNEST FLAGG, a citizen of the United States,residing at New York city, county and State of New York, have inventedcertain new and useful Improvements in Metal VVindow-Sashes, of whichthe following is a specification.

This invention relates to window construction and particularly to windowconstruction of the metallic type.

An object of the invention is to so shape, proportion and combine thevarious elements of a window, comprising sash, frame, etc., that thestructural qualities peculiar to bent metal will be employedadvantageously, to minimize the material and the labor necesfor. theconstruction of a satisfactory fireproof bent metal window.

In this general type of window it is customary to provide a sash and oneor more panes seated therein so that a metal surface or part is on eachside of the margin of a pane, the pane, therefore, being held positivelyby the sash against lateral removal I from either side somewhat as isthe case with a door panel.

In my co-pending application, Serial No. 356,553, I have claimed broadlya construc tion which provides for the ready removal of a pane, byarranging for the immediate detachment as an entirety of one or morerails of the sash, preferably the top rail and have shown ellic-ientmeans for connecting the removable rail to its abutting rails and alsoeiiicient means for securing said rail to a muntin, if a muntin is to beemployed. Inasmuch as this construction is closely related to andintimately associated with the invention set forth herein, I haveincluded an illustration and description of the same in this case.

Further objects are to provide an efficient bent metal muntin and bentmetal sash rail furthermore, to provide a sash comprising bent metalrails of the same cross section; and also to provide a suitable metallicwindow frame which will cooperate with such a ash.

Still further objects are to combine and adapt various elements so as tocooperate in furthering the general object of this invention.

Reference should be had to the accompanying drawings forming part ofthis specification, illustrating an em )odiment of the'invention and inwhich may be desired.

Figure 1 is a sectional elevation taken through line 11 of Fig. 2; Fig.2 is an interior elevation of the window but with parts broken away;Fig. 3 is a horizontal section through line 3-3 of Fig. 2, but showingthe window complete Fig. 4 is an enlarged (letail section taken alongline 4-4 of Fig. 2, but with the top sash lowered and the bottom sashraised Fig. 5 is an isometric view of a portion of the top rail of thelower sash and showing the corner angle iron; Fig. 6 is an isometricview showing the meeting rails of the top sash and the lower sash and.the interlockmg weather seal; and Fig. 7 is an isometric view showing indetail the end of a muntin in combination with two panes.

Referring now more in detail to the drawings:-1 designates the windowframe, which comprises jainbs 2 and 3, sill I, and head 5. The upper andlower sash are designated by 6 and 7, respectively. Sash 6, as shown,comprises stiles or vertical rails 8 and 0, top rail 10, bottom rail 11and muntin 12. The top rail of sash 7 is designated by 13, the bottomrail by 14, the right hand stile by 15 and the muntin by 16. 7

Although one muntin 12 is illustrated separating panes l7 and 18 in sash6 and one muntin loseparating panes l9 and 20 in sash 7, it is to beunderstood that each sash may be provided with any number of verticaland horizontal muntins, or with none at all, as In case none wereprovided, each sash would contain but a single pane.

It is preferred that each sash rail be of the same uniform cross sectionand preferably that shown in the drawings. The cross section of the sashrail is best shown in Fi s. 4 and 6. A single strip of sheet metal isbent on itself along longitudinal lines to form the molding 21, whichhas a flat face 22 substantially at right angles to face 23. The ed e ofthe metal strip cont inning from face 22 isbent out at right angles to22, then again at right angles to itself and then back at right anglesto face 22, as shown, to form part of a flange 25. The edge continuingfrom face 23 is bent out at right angles, then parallel with face 23and, on a line parallel with and flush with the outer edge of 23, it isdoubled back on itself. This bending forms a groove pane seat 24, whichis approximately alined with and substantially a counterpart of theflange 25 extending at right angles to face 22. This rail constructionmay be made in stock lengths; then cut into proper lengths for therespective sash rails, each rail being preferably mitered at its ends.

Figs. 4 and 6 show a preferable manner of connecting abutting rails..Some reinforcement, such as an angle iron 26, has one leg insertedwithin the hollow flange 25 of a rail end.

by suitable means, such as soldering, brazin or riveting, etc. In asimilar manner eac rail may be secured to the inclosed leg of the angleiron. It is, however, to be understood that the sash rails maybe joinedwithout the aid of the reinforcing angle iron 26. N evertheless, it ispreferred to employ the angle iron when joining the top rail pf each'sash to the abutting stiles. Figs. 4, 5 and 6. In this case the legs ofthe angle irons 26 are tapped to receive screws 27, which extend throughthe side of the flange 25 to clamp the parts together. removing thescrews 27, the to rail may readily be detachedand remover as anentirety. It may be replaced as readily. This feature permits a ane tobe slid home in the roove seats 24 lilge a shutter, where it may 5elocked in place by the attachin of the top rail. Cement28 may be used inthe seats 24. Any number of sash rails may be oined to the abuttingrails so as to be removable as an entirety, the same as hasbeendescribed in.

connection with the top rails.

The sash bar or muntin, shown in detail in Figs. 3 and 7, com rises twobent metal strips and means to c amp them together.

29 is a molding strip with its two edges 30 and 31 bent inwardly asshown. The edges 30 and 31 engage the interior face of the anes asshown. 'A second metal strip 32.

as each edge 33 and 34, doubled over on itself and then outwardly nearthe medial line of the strip as shown in Fig. 3. The outturned edges 33and 34 form spacing abutments. A strip or series of washers 35 engagethe edges 30 and 31 and by means of bolts 36 or their equivalent, whichpass between the edges of the panes l7 and 18 and suitably engage thestrip 32, the strip 32'is clamped towards the molding. The abutments 33and 34 limit the clamping effect of bolts 36 upon the two stri )s whichare preferably of such a depth t at the space between the strip 32 andthe edges 30 and 31 is the same as the width of the other pane seats 24.At each end of the muntin the molding 29 is cut off on a curve, so as tofit the molding of the sash rail, such as rail 10. The

Such a joint is shown in.

ma be clam ed a ainst t body portion of strip 32 is preferably squaredoff, leaving projecting tongues 33 and 34, being contmuations of theabutments 33 and 34. These tongues are designed to fit snugly in a paneseat 24 of the sash rail and secure the muntin. If desired, they may belong enough to penetrate the bottom of the pane seat .24 or may merelyengage the side walls of said seat and stop short of the bottom of thepane seat.

With a sash built up as described from rail construction of the sectionshown, there is provided a flange 25 on all the edges of the sash andextending at right angles to a flat face 23. This flange forms therunner memher and weather flange for the sash, particu larly that on thestiles.

Each jamb comprises a bent metal shell formed of a single strip ofmetal. The pulley face of each jamb is formed with an integral partingridge 35 with vertical side edges 36 and 37 at right angles to the faces38 and 39 of the jamb. The sash slide on opposite sides of these partingridges, as shown. The sash flanges 25slidably engage the vertical faces36-and 37 and are retained in place by vertical guides, preferably anglestrips 40 and 41, which are removably secured to the jambs-as shown.

Mounted in the jamb there'may be provided a clamping device or sashfast. Such a fast is indicated by 42. Its 'aws 43 and 44 he flanges 25through the ho es 45 and 46 provided in the vertical faces 36 and 37. i

Each jamb provides suitable runways for- X separating .strip 48 maybeprovided as shot n.

sash weights indicated by 47. v

49 indicates suitable pulleys over which theloords or chains, such as 50may run. Ren'iovabi sections may be provided in the jambs to giveaccessto their interior Such a section is indicated by 51.

In the embodiment of the invention illustrated the parting ridges 35separate the sash a sufficient distance to )ermit of the provision of asuitable interl ocking weather closure for the meeting rails 11 and 13of the two sash. Secured to flange 25 of rail 13 is-a bent metalhook-shaped strip 52, coo mating with a mating L-shaped bent metal curedto the flat face 23 of rail 11. These strips when interlocked completean S- shaped weatherclosure as shown.

'l he head 5 is similar to the jambs 2 and 3, but its parting ridge 54is narrower than the.

strip 53 se ridges 25 so as to allow clearage for strip 52 of the lowersash, when said sash is raised.

I Angle strips 55 and 56 are preferably al-liXed to the head shown, toclose againstthe flanges 25 of the top rails when a'sash is,

raised. V

The sill 4 comprises a bent metal shell open at the bottom andpreferably filled with concrete indicated by 57. Its upper face has anexterior inclined portion or shed 58. A l sash flanges to retain thesash; and clamping I horizontal ledge. 59 runs along its inner edge andpartly overlies tho shed 58. An angle strip 60 is preferably secured toledge 59 to face against the flange 25-01 the lower rail of sash 7. Thisflange may be provided with a depending weather strip 61 passing belowledge 59.

The various members of he frame may be joined by any approved means,known to the art, as will be understood.

The particular sash tainstruction described herein is covered by theclaims in my (0- l pending application, Serial No. 356,553,-filedFebruary 9, 1007.

It is to be understood that this invention is not limited to theembodiment shown and; that many parts may be modified within the scopeof this invention: flllllltllllOYO that many individual elements andcombinations of elements would be still within the scope ol' theinvention whencombined with widely varying window construction.

This invention comprises features which greatly cheapen windowconstruction of the class described; work a great economy in themaintenancev of the completed structure; while, as well, theconstruction possesses the qualities of durability and efficiency.
